What worries me is that SCSI2SD is a somewhat recent and well-known option but its availability was not so good about a month ago, and due to problems sourcing the components used in its design.  I got to thinking it might be useful to find out if the ZuluSCSI boards work because it appeared that they were slightly more available than either SCSI2SD or BlueSCSI.

Anyway, yeah it would be a good idea to have some idea what works and how well.

Thanks.  Just ordered one.  That probably will be helpful; through-hole component replacement with a soldering iron is something I can usually do successfully.  I had been thinking to cut into the top of the DS1287 so I could disconnect its internal battery and hook up a coin cell holder for a CR2032 and have got some of those on the way too.  (I have enough stuff that uses CR2032s to keep some on hand.)  But this would look better if someone thinks to look inside the case, and that it fits and works is good to know.
